SPECIFICATION forming* part Of Letters Patent N O. 548,029, datedOCtOber 15, 1895. Application led October 15, 1894.. Serial No. 525,969.(No model.)

To @ZZ whom t may concern.-

Be it known that we, JOHN T. BIBB, ofTacoma, in the county of Pierce,and ARTHUR T. TIMEWELL, of Spokane, in the county of Spokane, State ofWashington, have invented certain new and useful Improvements inAutomatic Sack Filling and Sewing Machines, of which the following is aspecification, reference being had to the accompanying drawings,

1o and to the letters and numerals of reference marked thereon.

This invention relates to means for sacking grain, ore, and othermaterials and for sewing the sacks after they are lled. It is designedto be an improvement on the invention disclosed in Patent N o. 476,7 78,granted to us June 14, 1892, and to which reference should be made.

In the drawings, Figure l is a perspective zo View of the machine. Fig.2 is a plan of the same. Fig. 3 is a plan, on an enlarged scale, of thesack-holder. Fig. 4 is a vertical section on the line zc, Fig. 2,showing the devices to close the sack-holder. Fig. 5 is a plan 2 5 ofthe table-top, several parts of the machine being removed; and Figs. 6to I3, inclusive, are details.

Similar letters and numerals of reference indicate similar parts in therespective figures. rhe table-top A is made of cast-iron or pressedsteel, with its edge a turned down, as shown. It is provided at one endwith adiamond-shaped hole a', from which aslot a2 eX- tends to near theother end of the table.

3 5 Flanges a3 are attached to or cast on the table-top to support andguide the sack-holder during its progress through the machine, and aseries of rollers a4 are arranged in the tabletop at the opposite sidesof the diamondy4o shaped hole a and the slot a2. The sackholder travelson these rollers through the machine, and they also serve to elevate itslightly above-the table-top to provide a space in which thesewing-needle can play, as will be described hereinafter. The table-topis supported by a series of legs B, (preferably made of T-iron,) boltedto thetable, as shown, and Ysuitably secured and braced at their lowerends by the frame b.

At each end of the machine a shaft C is journaled in suitable bearings cc, secured to the table-legs. These shafts each carry a sprocket-wheel cand two pinions c2 c2. The pinions c2 engage, respectively, racks cl d,attached to or forming parts of the ends of the frame D. Thesprocket-wheels c c on the shafts C C are connected by the chain c3, andone of the shafts C is provided with a crank c4. By operating the crankc4 both ends of the frame D may be elevated or lowered, as desired, theobject being to adjust the height of the frame to sacks of differentlengths. Journaled in the frame D are four rollers, three of which areshown-viz., e, e', and e2. The shafts of the rollers e and e2 extend beyoud the frameon one side thereof and are provided with sprocket-wheelsf f driven by the chainF, which latter is driven by the sprocket-wheel gon the counter-shaft G, which receives its movement from the maindrivingshaft H. A sprocket-wheel f2 is carried by a shaft journaled insuitable bearings on the frame b and serves as an idler around which thechain F runs. The rollers e and e carry the traveling bed or conveyer Eand those e2 and e3 the conveyer and shaking-bed E. When the machine isin operation, the traveling bed E moves continuously; but theshaking-bed E has an intermittent travel. This is accomplished asfollows: The sprocket-wheel f turns loosely on its shaft and carries onits inner face one half of a clutchft, (not shown,) the other half beingkeyed on the shaft and capable of being moved into engagement with thehalf on the sprocket-wheel by means of the rod f5, the latter beingoperated as hereinafter described.

Depending from each side of the frame D are brackets e' o', in whichshafts I I are mounted. Each of these shafts carries two eccentrics t"o" and each is provided with a crank i2, the cranks of the two shaftsbeingconnected by the rod is. The end of one of the shafts I isconnected to the lever J, and by rocking the lever the shafts I andtheir eccentrics i i will be partially rotated.

K is a frame having a convex top engaging the under side of theshaking-bed E. This frame K is within the frame D and adapted to have avertical movement. It is provided with four legs Za 7c Zo Za, eachhaving a caster k. The casters rest on the eccentrics t" t', and as thelatter are operated by the movement of the leverJ the frame K andshakingbed E will be given a vertical reciprocating movement, which willshake the grain or other material into the corners of the sack.

The sack-holder X consists of four channeled metal bars 1, 2, 3, and 4,hinged together at their ends, as shown in Fig. 3. A crosssection of thebar is seen in Fig. 6. The holder is normally forced open by the springs5 5 at the end joints. Near the ends are springaotuated claws (5 6, towhich the upper corners of the sack are attached, these claws be ingoperated in a manner similar to that described in our patent aforesaid.The sides of the sack are attached to hooks 7 7, hung on rods 8 8,adapted to have a sl-ight longitudinal movement iu the bars. The rods 88 are connected to levers 9 94011 the side joints ofthe holder, and theopening or closing of the latter effects the movement of the rods andthe hooks 7 7, hung thereon. `Secured within the channel of the barsl,2, 3, and 4 are a series of blocks l0 10, having inclined top surfaces.(See Fig. 7.) These blocks are so arranged that when the holder isopened the hooks 7 '7 will be caused to ride up their inclined surfacesand assume a horizontal position; but when the holder is closed thehooks 7 7 will move down the inclined surfaces and their points willhang down, `so that the sack will easily detach itself from them Whe-.ndischarged at the delivery end of the machine. The bars 1 2 3 4 on theirinner faces are each provided with a series of teeth 11 11 and recessesl2 l2. The teeth on one bar are adapted to the recesses of the oppositebar and serve to hold the sack when the holder is closed. The bars 1 and2 on their upper surfaces are provided with a series of teethfwhichform, when the holder is closed, a rack 13.

L is a lever pivoted at Z on the frame-of the machine. At equaldistances on each side of the pivot Z the vertical rods Z Z areconnected at their lower ends to the lever L. At their upper ends theserods Z Z are attached to t-he short arms of bell-crank levers Z2 Z2,pivot-ed in brackets Z3 Z3, depending from the under side of thetabletop.

M M are rods secured at one end to therim a of the table and at theirother ends to lugs m m on the under side of the `table-top. The

lugs .m m are provided with apertures through which the barsNNslide.Each of these bars is -upturned at its front end, andthe upturnedportions fn 'n when in their normal positions project above thetable-top and occupy the recesses n n at the side angles of the openingct in the table-top. The rear ends ofthe bars N N havedownwardly-projecting lugs n2 n2, which slide on the rods M M and areconnected by links Z4 Z4 to the long arms of the bell-crank levers Z2Z2. Spiral springs m m are titted on the rods M M between the lugs n2and m and serve to maintain the bars N N in their normal positions.Vthcn the sacloholder is open and in place around the opening a in thetable-top, the ends n n of the bars N N will engage the side joints ofthe sack-holder, and when the lever L is operated the bars N N will becaused to approach each otherand thereby close the sackholder. Themovement of the lever L also effects the movement of the rod f5, thelatter being connected atits upper end to the upper end of one of thevertical rods Z', thus partaking of its movement.

The counter-shaft G carries two pulleys g g and a spur-gear g2. Anothershaft O is journaled in suitable bearings o o on the table-top. Thisshaft also carries two pulleys o o and a spur-gear o?, corresponding tothe similar elements on the counter-shaft G. The shaft O is positivelydriven by the sprocketchain o1 from the shaft G. Belts c3 03 are drivenby the pulleys g and-o andare for the purpose of returning thesack-holder from the delivery end of the machine, afterthe sack isreleased from it, to the opening a. The spur-gearsg2 o2 are adapted toengage the rack 13 on the top ofthe sack-holder and aid in drawing theholder and sack through the machine.

Pis a tube secured by suitable means to the under side of the table-top,and within this tube is a rod 79, with a surrounding spiral spring p.The rod p is free to have longitudinal movement in the tube P and whenpushed outwardly will compress the spring 19. The forward end of the rodp is bent at an angle and provided with a head p2, which 4projects upthrough the slot a2 in the tabletopin the path of the sack-holder X. Asthe holder and sack travel through the machine, the rod p will be pushedforward against the force of the spring 1J until the holder opens `andbecomes disengaged from the sack, when the force of the spring p willretract the rod pand force the sack-holder up the inclined bars Q Q ontothe belts 03 03, which latter will return it tothe operator. The flangesai on the table-top are arranged in a diamond shape at theidelivery endof the machine to permit the sack-holder to open by the force of thesprings 5 5.

The bars Q Q are pivoted at one end to the table and normally lie in theslots q q in the table, their free ends being supported by triggers qq', (see Figs. 5 and 11,) pivoted on the under side of the table. Fachtrigger is operated by a rod q2, adapted to slide in bear ings securedto the table. These rods are held in their normal position by springsg3. Only one bar Q and its elevating mechanism is shown in Fig. 1l; but`it is to be understood that the other bar Q is actuated in a similarmanner. The rods q2 are operated by bellcrank levers g4, connectedeither to the le ver L or the rods Z. The movement of the lever Ltherefore effects three operationsviz., closing the sack-holder,bringing the two IIC halves of the clutch (not shown) into engagement,and lifting the bars Q Q.

The sewing device is indicated as a whole by S, the needle beingindicated by s. The needle reciprocates immediately above the table-topand enters the sack close below the sackholder, the rollers a4 elevatingthe latter a suflicient height above the table-top to permit thisaction. The flanges 0.3 are cut away for the passage of the needle.

As we do not limit ourselves to any special form of sewing device,itneed not be further described herein, and reference is made to oursaid former patent as illustrating one form of mechanism to perform thesewing.

The general operation is as follows: The sack-holder X. is placed in itsopen position over the opening a and the sack attached to the hooks 6and 7. The grain or othermaterial is then fed into the sack, and duringthe lilling the operator rocks the lever J, which imparts to theshakingbed E a vertical reciprocating movement and shakes the materialdown into the corners of the sack and aids in packing it closely in thesack. When the sack is lilled, the operator depresses the lever L, whichmovement closes the sackholder, brings the two halves of the clutch f4into engagement, and thereby causes the shaking-bed E to travel, andelevates the free lends of thebars Q Q. The spur-gear g2 will now engagethe rack 13 on the sackholder, and the sack will travel through themachine, being sewed during its passage. The spur-gear o2 will alsoengage the rack 13 and continue the forward movement of the sackholder,which will push the head p2 and rod p forward with it. When thesack-holder reaches the triangular shaped part of the flanges d3, thesprings 5 will force it open and the sack will become detached from it.At the same time the spurgear o2 will be disengaged from the rack 13,andthe rodp will be retracted by the spring p and carry the sack-holderwith it, causing the latter to ride up the rods Q Q onto the belts o305, which latter will return it to the operator ready for the attachmentof another sack.

Having described our invention, we claimn l. In a machine for fillingand sewing sacks, the combination with a table having an opening and asack holder adapted when open to lit around said opening, of springretracted bars engaging the sides of the sackholder, a lever, rods,bell-cranks and links connecting the lever and said bars whereby thesackholder is closed, substantially as specified.
